Swamp rabbits exist at the northern fringe of their range in southern Illinois, with their major local stronghold being the Cache River basin. Swamp rabbits have declined in this region due to loss of bottomland hardwood forests, but may respond positively to federal farm programs that create early-successional habitats.
